I'm trying to figure a way for an agressive sounding exaust setup for a GN. Have any of you guys heard the loudmouth exhaust for an fbody? I was thinking of buying the resonator used in this system and having a shop put it on a 3" pipe. Has anybody done this before? If you need to hear how the system sounds on an f body, go to the fbody shop online and choode sights and sounds, then the exhaust selector, then for an LS1 car, then click on the link for the loudmouth. Let me know what you think.
